[0024] In a preferred embodiment, a square groove 10 is provided on the outer wall on the right side of the outer shell 1, and the clamping mechanism 8 is located on the right side of the movable support block 7, so that the movable support block 7 drives the clamping mechanism 8 to move to the right, so that the clamping mechanism 8 is located on the outside of the outer shell 1. At this time, the test tube 9 on the clamping mechanism 8 can be installed and removed, thereby improving the rationality of the device.

[0025] In a preferred embodiment, a curved pipe 51 is installed at the bottom of the funnel 2 5 , and the length of the curved pipe 51 is smaller than the diameter of the test tube 9 , so that when sulfuric acid flows on the funnel 2 5 , the sulfuric acid can flow downward along the inner wall of the funnel 2 5 , so that the device complies with the detection process.

[0026] In a preferred embodiment, the clamping mechanism 8 includes a fixed bracket 801, a threaded hole 802 is provided on the outer edge of the fixed bracket 801, a limiting groove 803 is provided on the inner wall of the fixed bracket 801, and a clamping block 804 is slidably connected to the inner wall of the limiting groove 803, so that the clamping block 804 can move in the limiting groove 803, so that the clamping block 804 will not rotate when moving, thereby improving the rationality of the device.

[0027] In a preferred embodiment, the outer wall of the clamping block 804 is fixedly equipped with a connecting block 805, and the inner wall of the connecting block 805 is movably connected with a threaded rod 806, and the threaded rod 806 is threadedly connected to the threaded hole 802.

At this time, the threaded rod 806 pushes the clamping block 804 to move in the limiting groove 803. When the clamping block 804 contacts the test tube 9, the test tube 9 is clamped. Then the funnel 1 4 and the funnel 2 5 are lifted, and the movable support block 7 is moved to the bottom of the funnel 1 4. At this time, the funnel 1 4 is put down, and the reagent is added to the test tube 9 through the funnel 1 4. Then the funnel 1 4 is lifted, and the movable support block 7 is moved to the bottom of the funnel 2 5. At this time, the curved pipe 51 on the funnel 2 5 contacts the inner wall of the test tube 9, and sulfuric acid is added to the funnel 2 5. At this time, the sulfuric acid flows down along the inner wall of the test tube 9, and then the funnel 2 5 is lifted, and the movable support block 7 is moved to the rightmost side.
